Topic: [ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX] - page 411. (Read 3426938 times)

Hey nice. Thanks you for your details.
I have the same board too. I use Linux and all of my 7 cards get recognized instantly without any pin to be shorted. I only need to change the 3. PCIE16 slot in BIOS to gen2 to recognize the 7. card.

But problem comes when I started ccminer. The machine crashes instantly and restart. I have look at all the logs but found nothing. It seems like the board won't deliver enough power for all 7 cards. Of course I use power risers on all cards.

It is very strange but I still don't have time to test more. Im staying with the 6 cards setup with Asrock H81 BTC pro now.

i use asrock z87 fatality killer. all x1 slots need to be shorted the presence pins, and all x16 slots need x16-x16 risers. I use powered risers for all slots. tip: i had to do discovery in bios b4 proceeding to windows.

if u still want to do a 7gpu setup, try this:

[1] in bios, turn off integrated gpu,
[2] turn off other peripherals (like sound, com ports) because these will occupy system resources, prevent ur 7gpus from being detected.
[3] do 1 by 1 gpu discovery in bios. meaning, detect 1, reboot. detect 2, reboot. detect 3.. and so on
[4a] windows itself was not a pain for me, maybe coz i already had a win7 installation set up and waiting in the SSD.
[4b] so u can do this way, if u want: install few gpus first, like 3 or 4, then do ur mining. when everything works fine, then that's the time u go for all 7 gpus

ok, now i will tell u why u should avoid skimping on cpu and memory: earlier versions of ccminer tend to hog cpu resources. this prevent gpus from achieving peak hashrate.

recall that ccminer 0.4 and 0.5 heavycoin mining used to need multiple instances of ccminer, only 2 gpus per instance? in my case, with g3220 cpu and 8gb ram, i can only do 3 instances of 2gpus each with tolerable hashrate performance. if i launch the 7th gpu, in its own window, or along with the 3rd window (3gpus in it instead of 2gpus), the whole rig slows down to 70% of hashrate. running 1 instance with all 7 gpus had , of course, worse performance.

note, that above is not complaint. mining programs are work in progress, so i'm just sharing my experience this way: if u want to use multi gpu rig, and don't mind spending a few extra dollars on cpu and memory, u won't be sorry. i know there is the temptation to be min-maxing our hardware specs, but in reality such is not necessary. it feels good to save a few dollars, that's all. like it feels good to trade ur coins are higher value than lower, even if the actualy sum of money is just a few cents difference.

Anyway, c&c are continuously doing great job with the optimizations. now my 7gpu 750ti rig does correct hashrate with just 1 ccminer instance: 14.7mhs for x11, 25.5mhs - 27mhs for jpc. they are the best thing to happen to nvidia, honestly. Thank you profusely, kind sirs! =)

I think x13 or some other algo might become the next x11 within the next couple of months. x11 is becoming ridiculous with total net hashrate. It's growing at alarming speed. The next hot x11 coin gonna hit 1 TH. I am sure more than half of those hashrate doesn't come from gpu.

Nice to see someone got it running. I have tried a lot of mainboards for the 7 cards combi but all of those failed. Of course I only use cheap CPU and 4GB Ram. Which mainboard do you use for your rig?

jackpoint is still very profitable, with one rig 6 x 750ti you can do about 150k coins per day, price is 15s, math tell me that it does 0.0225, which i find very good

till yesterday XC was nice. but the mining period is over now.
right now I don't see a clear oportunity.
 
yac could be a chance to mine & hold a few days... because the N factor changes end of the month.

EDIT:
@amph: JPC get down through the sell pressure...

@jack: DRK diff is far to high... I did not get 1 DRK a day with 28MHs!
i like this coin, but buying is the better way to get it.

0.02 with jackpotcoin, and a 0.015 if you search for some ignored x11 coins, like wincoin/maybe supercoin, but they are dying you need to dump fast

x11coin also was profitable yesterday, if you shift between all those crap out there it is possible to stay in the 0.015-0.02 range with a 6 x 750ti rig

Difficulty darkcoin is too high , in one day with 4.4 mh/s i have only 0.08 DRK .

How are the profits these days? Any increase/decease compared to the levels earlier this month? Coinwarz is not helping much because it doesn't include many CPU and X11 coins.

cbuchner1 ,  any good news for ccminer before end of this month ? 

How much does amount of CUDA cores influence hash rate on X11?

How much mhs can get GeForce 770 Asus DC2OC-2GD5?

Correct on the 6 cards running fine. I made no special adjustments to my system, and am using the stock drivers available from Nvidia.

Have to be patient with the discovery and installation of the driver over and over (or whatever it is doing), but it takes a while just starting at that hardware discovery and installation bar...

16gb are too much anyway, 8 are more than enough, i read that 6 gpu should be recognized easy with win 7 64bit, you don't need any modded drivers

it is a pity, and the price of this coin up goes

Question, If I am running ccminer50,  I wanted to also run a CPU mining program, but if I do it stops ccminer, is there a way to do this?

Are you asking if ccminer works for x13? No, not currently.

somebody tried to launch?
